Note:
• When you use this method to set the torque limit, it enables the lower torque limit:
–Set H3-02, H3-06, or H3-10 = 10, 15 [MFAI Function Select = Forward, Reverse/Regenerative Torque Limit].
–Use a communication option to set the torque limits
• You must think about drive capacity when a large quantity of torque is necessary. If you set the value too high, the drive can detect oC
[Overcurrent].
• If you set the value too low with large loads, the motor can stall.
■ L7-02: Reverse Torque Limit
